John found these photos within the Bundesarchiv in Germany and put this history together. Thanks for sharing!
The first one is in Berlin, taken June 1, 1948. the German caption reads: Amerikanische MP. fährt mit armierten Jeeps und Panzern am Tage der Währungsreform durch die Westsektoren Berlins. (American MPs travel with armed jeep on the currency reform day thru the west sector of Berlin)
The second photo has a similar caption and is dated the same day.
The third one is also in is Berlin, but it is dated in May 1, 1950. It is at the Brandenburg Gate looking into the Soviet Sector from the British Sector, which starts almost behind the jeep. The gate is actually inside the Soviet Sector.
The Gate today, from the opposite side.
